Abstract:This research presents two helical capillary tube sizing charts for R407C and R410A, two correction charts for another tube size, and a correction chart for all mixture ratios of R125, R134a and R32. These charts are obtained from the homogeneous flow model including the effect of gravitational force. It is verified by comparison with experimental data obtained from the published literature. From the model, the sizing charts for a diameter of 1.63[Formula: see text]mm, length of 2.03[Formula: see text]m, and h… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
